Be sure to ask specifics on what device you were clocked with; name of mfg, last date of calibration, and most important the standards used to calibrate. I have a buddy who got out of a ticket in Ohio because the radar unit was not within the calibration interval - his lawyer added that he could have gotten off if even the "standards" used to calibrate were not within their their calibration interval.
Ohio does have provision for remedial drivers course, but only for point reduction, and only once per lifetime . . . I burned mine back when I was a dumb young kid. Guess it helped - I have not had a ticket for several years. But I sure like to push it with my 300SD - seems to glide at about 90!
